Driving and Operating 9-35
When going up steep hills,
you might have to step on the
accelerator pedal to maintain
the vehicle speed. When going
downhill, you might have to brake
or shift to a lower gear to keep the
vehicle speed down. When the
brakes are applied the cruise
control is disengaged.
Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal.
.Press the[button.
.To turn off the cruise control,
press
Ton the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
the
Tbutton or if the ignition is
turned off.
Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it operates at speeds less than
8 km/h (5 mph), and assists the
driver with parking and avoiding
objects while in R (Reverse).
The sensors on the rear bumper are
used to detect the distance to an
object up to 2.5 m (8 ft) behind the
vehicle, and at least 25.4 cm (10 in)
off the ground.
{WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.Objects that are below the
bumper, underneath the
vehicle, or too close or far
from the vehicle.
.Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing, vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors.

9-50 Driving and Operating
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move that hand
to the left. To move the trailer to
the right, move your hand to the
right. Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument panel flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping. When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a
lower gear before starting down
a long or steep downgrade. If the
transmission is not shifted down,
the brakes might have to be used
so much that they would get hot and
no longer work well. See
“Automatic
Engine Grade Braking” withinTow/
Haul Mode on page 9‑28.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.

of air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in psi (pounds per
square inch) or kPa (kilopascal). Accessory Weight

combined weight of optional
accessories. Some examples
of optional accessories are,
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
Aspect Ratio

of a tire's height to its width.
Belt
:A rubber coated layer of
cords that is located between
the plies and the tread. Cords
may be made from steel or other
reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim. Bias Ply Tire
:A pneumatic
tire in which the plies are laid
at alternate angles less than
90 degrees to the centerline
of the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. See Tire Pressure
on page 10‑45.
Curb Weight
:The weight of a
motor vehicle with standard and
optional equipment including
the maximum capacity of fuel,
oil, and coolant, but without

Vehicle Care 10-61
If a Tire Goes Flat
It is unusual for a tire to blowout,
especially if the tires are maintained
properly. See Tires. If air goes out of
a tire, it is much more likely to leak
out slowly. But if there is ever a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip
the steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.AA rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction
as used in a skid. Stop pressing
the accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently
brake to a stop, well off the road,
if possible.
{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has
been driven on while severely
underinflated or flat may cause
a blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon
as possible.
{WARNING
Lifting a vehicle and getting
under it to do maintenance or
repairs is dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6‑3.

Once the destination is reached:
1. Set the parking brake.
2. Reinstall the fuses in theunderhood fuse block.
3. Shift the transmission to P (Park), turn the ignition to
LOCK/OFF and remove the
key from the ignition.
4. Disconnect the vehicle from the towing vehicle.
Notice: Do not tow a vehicle
with the front drive wheels on
the ground if one of the front tires
is a compact spare tire. Towing
with two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.Dolly Towing
(All-Wheel‐Drive Vehicles)
All-wheel‐drive vehicles must not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.
Dolly Towing
(Front-Wheel‐ Drive
Vehicles Only)
To tow a front-wheel‐drive vehicle
from the front with two wheels on
the ground:
1. Put the front wheels on a dolly.
2. Move the shift lever to P (Park).
3. Set the parking brake.
4. Clamp the steering wheel in a
straight-ahead position with a
clamping device designed for
towing.
